Hydraulc Double Boom Drilling Jumbo Double Boomer

CMJ2-17 All Hydraulic Crawler Drilling Jumbo
CMJ2-17 All hydraulic crawler drilling jumbo is mainly used to drill blastholes for tunneling construction in coal mine, nonferrous metal mine, hydro-power station, railroad, highway engineering, etc. The jumbo is designed with two drilling booms, advanced hydraulic rock drill system, self-return and anti-jamming mechanism for making it has rapid drilling speed and high efficiency. Flexible mechanism can make the jumbo drilling on face, slope, roof, side wall and floor in underground mine or tunnels, and it also can drill anchor holes upward. With modular designed, this small compact jumbo has a low center of gravity, great mobility, remarkable stability and strong climb capability thus can improve working environment and get efficiency, quality development.Jumbofeatures
